*Not supported.

†Only condenser pump sequence 1 is supported.

NOTES:

1.Flow checked if pump off needed when a command is sent to the primary pump to prevent cooler from freezing in winter conditions. Command will set the cooler flow switch to closed while the controls stop the cooler pump. The controls may then generate an alarm. If this decision is active, the cooler flow switch is not checked when the cooler pump is stopped.

2.If cooling reset select set point has been selected the set point based on 4-20mA input signal through ComfortLink™ control, then a 4-20 mA reset

function shall be ignored. Configuration 3 (4-20mA Control) and 4 (Space Temperature) shall require an Energy Management Module.

3.Configuration 2 (4-20mA Control) shall require an Energy Management Module. Configuration 1 Switch Demand limit provides 3 step demand limit if an Energy Management Module is present. Otherwise, only one step is allowed.

4.Reverse Alarms Relay configuration will be deenergized when an alarm and alert relay is present and will be energized when no alarm is present.
